I'm happy for anyone to commit changes to the code, I didn't have a mailserver
that supported quota when I ported it from the config file examples.
I'm just confused as to how to differentiate between these cases:

User has no mail but a quota (eg new user)
 - You get empty array (what to show? error?)

User had no qouta set and may or may not have messages.
 - You get empty array (show NO LIMIT)
